Phobia.

Mostly likley he was alone? He was mentally scarred, still traumatized by this accident, and the need for someone on the passenger seat indicates he needs constant reassurance. Needs to see a shrink as @ jamplu has pointed out to come to terms and put this accident behind him.

You can always Google the word.

I think it is normal.........I think he is still traumatized from his accident and feels safer when there is someone else in the car. I have the same fear too partly because i had an accident and partly because i am just scared of driving. Actually right after the accident,i would be on the passenger seat and keep 'instructing' my bro what to do and pointing at all dangers on the road-real or imagined,i could see a dog crossing the road from very far away .
Needs Help well maybe maybe not? well i do not think so,i think it will go away slowly......the more the pressure,the more irritating it will get for him. Now i can drive.....at a very slow speed,short distance and mostly in the village

Sad thing..he doesnt touch family car. 6yrs is a loong time not to have healed. True, he was alone when the accident happened.

Seems the phobia was triggered by the Accident. As famooz has said, i strongly believe it will slowly go away...but some effort has to be put in place so as to get over the fear. Since he can still drive when there is someone on the passanger seat, i would recommend you encourage him to start using the car for short distances especially when running local errands...i.e going to the supermarket within the estate, or taking the car for a short drive within the estate. that will help him slowly develop confidence and in-turn get over his fears. Also if he happens to give you a ride as a passanger, compliment him for being a good driver. That will do wonders.

We have many lunatics on the road such that at times you would wish to simply sit back and let someone do the driving. As a newbie driver there are several times I left the car parked as I hopped into a jive.

I can imagine what the dude is going through especially after the accident. It can be traumatising but then Njenga and co could possibly help him out.

Helped? By asking him not to drive at all - this is a powder keg on our roads, am afraid to say so.

@mpobiz..what do u mean? Pls elaborate. I remember once he told me he had a panic in kiambu rd and he hit a mat from behind. U can imagin the chaos. To the extent after he paid them, couldnt drive that day and had to hire a driver to take him home.

...Drive with him/her along Mombasa road. Plough through that herd of Maasai cows crossing the road. As you do this keep laughing...Pack the car beside the road...Take out your laptop and start Wazuaring as you wait for the cops. Pretend that what has happened is a very small thing...
